A coastal monitoring technician takes the overnight watch at a Foundation lighthouse on the northern Oregon coast after the previous keeper requests reassignment and leaves one note in the logbook: "The most beautiful shift I have ever worked, and I cannot work it anymore, because the light is no longer alone." The beam sweeps the ocean every ten seconds. On her fourth night, the photometer — aimed at bearing 215, open ocean, four hundred kilometres of nothing — registers a return. A point of light at the water's surface, producing its own beam, sweeping northeast, toward the lighthouse, at the same speed, the same colour, the same rotation. Two beams, sweeping toward each other across dark water, crossing every five seconds. Each night the answering light is 0.2 candelas brighter. There is no structure on that bearing. There is no vessel. There is no land. A light is answering the lighthouse from a point on the ocean where nothing has stood for a hundred years. The Night Archivist presents the recovered watch log and one entry in the 1923 Lighthouse Board records that explains everything except how a lighthouse that was never built learned to sweep. This is a recovered Foundation encounter presented for slow nighttime listening. The narration is calm and unhurried across approximately one hundred minutes, with no jump scares, no sudden volume changes and no sounds designed to startle you awake.
